Sex book‧Calling

Why do men fall asleep after sex? 終於到手：
Can animals commit suicide?
Can animals masturbate?
Should a man wait several days between sex to store up sperm if trying to impregnate his wife?
Can you breastfeed with fake boobs?

我喜歡這兩個答案(excerpts)：

Why do men fall asleep after sex?

Leave it to a ninety-two-year-old woman to break down a complicated question into the simplest terms. When we told Billy's wife's grandmother the name of our new book, she answered in a second, 'Because they work so damn hard!"

Does standing on your head after sex increase your chances of becoming pregnant?

There is no evidence to suggest that standing on your head will help at all, although it would be very interesting to try to have sex while standing on your head. If u don't conceive you could at least get a job with Cirque du Soleil.

最近有很強烈的感覺，有什麼事情我要做，近乎宿命的。
I heard the calling, but i am not there yet.
想來想去。
What have i missed out?
